FaaS vs SSH
FaaS (Function as a Service) and SSH (Secure Shell) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: FaaS refers to function as a service, while SSH refers to secure shell — they describe different things even when they show up in the same sentence.
FaaS — Function as a Service
A cloud model where you ship individual functions and the platform handles servers, scaling, and idle time. Pay-per-execution makes it brilliant for spiky workloads and brutal for steady ones.
SSH — Secure Shell
An encrypted protocol for accessing and operating remote servers. Still the backbone of how engineers touch production — which is why SSH key hygiene is non-negotiable.
